通过理想高通滤波器实现对图像的锐化，图像锐化的目的是突出图像的边缘信息，加强其图像的轮廓特征，以便于人眼和机器的识别。-Through the realization of the ideal high-pass filter for image sharpening, image sharpening is designed to highlight the edge of the image information, to enhance the outline of the charact

基于matlab图像处理功能实现，包括滤波，锐化，fft等-function of image processing based on matlab

用matlab语言编写代码，实现功能包括图象的读取、存储、显示、直方图均衡化、阈值化、小波分解、小波重构、加噪、去噪、平滑、锐化、边缘检测、图像分割等- using matlab language to write code to achieve functionality, including image reading, storage, display, histogram equalization, thresholding, wavelet decomposition, wavelet
